The Magic of Lotus Flowers
Lotus flowers are symbols of purity and strength in many cultures. They grow in muddy water but stay clean and beautiful. Their roots store nutrients in underwater stems, helping them live through cold winters. Lotus leaves do not absorb water, so raindrops roll off like shiny pearls. Interestingly, lotus flowers close at night and open again in the morning, like magic.
These flowers are not only pretty but also useful. People use lotus seeds in traditional medicines and cook them in soups. In some Asian countries, lotus stems and leaves are eaten as vegetables. Lotus plants also provide homes for fish and frogs in ponds, making them important to freshwater ecosystems. Their roots even help clean water by taking in harmful things.
